Making No-Wax Tile Floors Shine

I have no-wax tile floors and I am looking for advice on how to make them shine using natural ingredients. Is their any other products besides Mop-N-Glo? I live in the desert and my floors stay gritty when the windows are open because the sand blows in. Any advise?

A friend of my mon's long time ago used to use an old fluffy dist mop head that she used only for shining her floors---she would spray plain store brand Windex on the floor, and buff it with the mop head, using her feet. It always made her floors shine. I live in the country, and have dust constantly on mine, but I guess if I kept my windows and doors shut all the time, and just ran the a/c all the time, that would solve it.
